Now, in fact, the production technology of aluminum alloy windows is very mature. Pay attention to the following points when selecting, and there is basically no problem.

Look at the material

Excellent aluminum alloy screens are generally made of aluminum, and the thickness, hardness and oxide film are in line with the regulations of relevant departments. The wall thickness should be above 65438 0.2 mm, the tensile strength should reach 65438 057 Newton per square millimeter, the bending hardness should reach 65438 008 Newton per square millimeter, and the oxide film thickness should reach 65438 00 micron ... If the above requirements are not met, it is a fake aluminum alloy screen window and cannot be bought.

mark

Production enterprises that meet the requirements or standards will mark the product identification in a prominent position of their aluminum alloy products, including the name and trademark of the production enterprise, product name, product model or logo, production time or serial number, etc. The packaging paper of its products has obvious words or signs such as "moistureproof", "handle with care" and "upward". If there is such a mark, it is a qualified product.

Look at processing

Excellent aluminum alloy screen window, exquisite workmanship, exquisite device, good sealing effect and convenient opening. Fake aluminum alloy screen window, perfunctory workmanship, not installed as required, poor sealing performance, not easy to open and close. The inferior quality aluminum alloy screen window is not only prone to water leakage, wind and rain, but also cracks the glass. At the same time, in bad weather, the glass is easy to scratch when it falls.

Choose by brand

In addition, you can also choose by brand. Big brands like New Hausen and Fu Xuan are all good.
